Troubleshooting

Installation and Configuration

Refer to the DAQ Getting Started Guide for general installation and configuration instructions.

For LabWindows/CVI users, if the Data Acquisition function panel is disabled, you may need to uninstall NI-DAQmx and reinstall it, making sure that you add support for LabWindows/CVI. If you have installed LabWindows/CVI support and Data Acquisition is still dimmed, select Library» Customize . In the Customize Library Menu dialog box, check Data Acquisition, and restart LabWindows/CVI. You might also need to verify that the dataacq.lib is in the bin directory.

Programming

To help you get started programming, you can use the examples in your ADE.

You can also visit NI's extensive library of technical support resources at ni.com/support.

You can interactively configure global virtual channels and tasks with the DAQ Assistant. For NI application software such as LabVIEW, you can use the DAQ Assistant to generate code.

Note

I/O Trace is not supported by the NI-DAQmx .NET API.

External Connections

In addition to the information on making signal connections in this help file, the Connection Diagram tab in the DAQ Assistant within MAX shows you how to connect signals.

Calibration

• For information on externally calibrating your device, including step-by-step calibration procedures, refer to ni.com/calibration.
• For an overview of calibration, including the difference between self-calibration and external calibration, refer to Device Calibration.
• For device-specific information required for calibration with NI-DAQmx, refer to Device Calibration Considerations.
• For information on channel calibration, refer to Channel Calibration.

CPU Usage

NI-DAQmx tasks use 100% of the CPU if no other processes are running. However, as soon as another process requires the CPU, the NI-DAQmx task yields to that process.
